I followed this thread and my opinion is, that at least in education
area axes trough the origin are often used. So I ended with the
following function, which places labels at the end of the axes and plot
any Graphics3D with axes:

NoOpt[x__]:=And@@(Not[OptionQ[#]]&)/@{x}

SyntaxInformation[AchsenStattPlot]=
    {"ArgumentsPattern"->{_,_.,_.,_.,_.,OptionsPattern[]}};
AchsenStattBox[g_Graphics3D,
  achsenOrigin_: {0, 0, 0},
  labFakt :(_Real | _Integer | _List) : 1.2,
  labColor_: Red,
  labSize_: 16,
  opts:OptionsPattern[]]/;NoOpt[achsenOrigin,labFakt,labColor,labSize]:=
 Module[{labels, o = achsenOrigin, xmax, ymax, zmax, lx, ly, lz},
  If[Head[labFakt] === List, {lx, ly, lz} = labFakt,
   {lx, ly, lz} = ConstantArray[labFakt, 3]];
  {xmax, ymax, zmax} = #[[2]] & /@ AbsoluteOptions[g, PlotRange][[1, 2]];
  labels = {
    Text[Style["x", labSize, labColor], {xmax lx, o[[2]], o[[3]]}], 
    Text[Style["y", labSize, labColor], {o[[1]], ymax ly, o[[3]]}], 
    Text[Style["z", labSize, labColor], {o[[1]], o[[2]], zmax lz}]};
  Show[{g, Graphics3D[{labels}]},
    AxesLabel->None, Boxed -> False, AxesOrigin -> o,Evaluate[opts]]
  ]
